摘要:	本研究主要是提出一種新的線型光學式三角量測系統，藉由將雷射光束打在圓柱透鏡上形成一條細長的雷射線型光束，將其投射在待量測物體表面上，並用影像擷取裝置擷取光束因待測物體表面之起伏而産生形變之影像，傳輸至電腦，再用自撰的軟體分析影像，即可量測出物體表面之輪廓及位移資訊。線型光學式三角量測系統經過一系列系統校正實驗及實際上的應用後，證明了本系統相當可靠且準確度高，與舊系統架構相比之下，本系統在單次可量測到的資料量有著大幅度的進步，最多可同時量測640個資料點，而本系統最小解析度達到10.20μm(0.1pixel)。而系統應用於物體表面輪廓之分析，如鏡片輪廓量測、尺寸量測及中醫脈象量測，有著非接觸式量測系統之優點，可免於量測時破壞物體表面。This study develops a new linear optical triangulation measurement system by projecting a laser point onto a cylindrical lens to form a long linear laser beam. We project this linear laser beam on the surface of objects, and capture image information due to surface deformation by capture device , then transfer this image to computer. Finally, we use image analysis software to process this image , so that, we can measure contour information and the displacement information of surface of objects. After a series of alignment experiments, proof that linear optical triangulation measurement system is a reliable system. Compare with old triangulation measurement system, linear optical triangulation measurement system can measure up to 640 data points in a single measurement progress at the same time, and resolution of this system is 10.20μm (0.1pixel). The system can apply to analysis of surface contours, such as the lens profile measurement ,size measurement, and pulse measurement of Chinese medicine. It has an advantage of non-contact measurement, and it also can prevent surface damage from process of measurement.
